Pressure-induced dimensional crossover in a kagome superconductor
Fanghang Yu, Xudong Zhu, Xikai Wen +9
The recently discovered kagome superconductors AV3Sb5 exhibit tantalizing high-pressure phase diagrams, in which a new dome-like superconducting phase emerges under moderate pressu…
A new class of bilayer kagome lattice compounds with Dirac nodal lines and pressure-induced superconductivity
Mengzhu Shi, Fanghang Yu, Ye Yang +11
Kagome lattice composed of transition-metal ions provides a great opportunity to explore the intertwining between geometry, electronic orders and band topology. The discovery of mu…
Kagome superconductors AVSb (A=K, Rb, Cs)
Kun Jiang, Tao Wu, Jia-Xin Yin +5
The quasi two-dimensional (quasi-2D) kagome materials AVSb (A=K, Rb, Cs) were found to be a prime example of kagome superconductors, a new quantum platform to investigate t…
Locally commensurate charge-density wave with three-unit-cell periodicity in YBCO
I. Vinograd, R. Zhou, M. Hirata +7
In order to identify the mechanism responsible for the formation of charge-density waves (CDW) in cuprate superconductors, it is important to understand which aspects of the CDW's…
Superconducting fluctuations in overdoped BiSrCaCuO
Yu He, Su-Di Chen, Zi-Xiang Li +13
Fluctuating superconductivity - vestigial Cooper pairing in the resistive state of a material - is usually associated with low dimensionality, strong disorder or low carrier densit…
Mapping the Dirac fermions in intrinsic antiferromagnetic topological insulators (MnBiTe)(BiTe) (n=0, 1)
Zuowei Liang, Mengzhu Shi, Qiang Zhang +7
Topological surface states with intrinsic magnetic ordering in the MnBiTe(BiTe) compounds have been predicted to host rich topological phenomena including quant…
Evidence for negative thermal expansion in the superconducting precursor phase SmFeAsO
H. D. Zhou, P. M. Sarte, B. S. Conner +8
The fluorine-doped rare-earth iron oxypnictide series SmFeAsOF (0 0.10) was investigated with high resolution powder x-ray scattering. In agreement with p…
Spin susceptibility of charge ordered YBa2Cu3Oy across the upper critical field
R. Zhou, M. Hirata, T. Wu +9
The value of the upper critical field Hc2, a fundamental characteristic of the superconducting state, has been subject to strong controversy in high-Tc copper-oxides. Since the iss…
Structural Changes Related to the Magnetic Transitions in Hexagonal InMnO3
T. Yu, T. A. Tyson, P. Gao +4
Two magnetic ordering transitions are found in InMnO3, the paramagnetic to antiferromagnetic transition near ~118 K and a lower possible spin rotation transition near ~42 K. Multip…
Incipient charge order observed by NMR in the normal state of YBa2Cu3Oy
T. Wu, H. Mayaffre, S. Krämer +6
The pseudogap regime of high-temperature cuprates harbours diverse manifestations of electronic ordering whose exact nature and universality remain debated. Here, we show that the…
Pressure Dependent Structural Changes and Predicted Electrical Polarization in Perovskite RMnO3
T. Wu, T. A. Tyson, H. Chen +7
High pressure x-ray diffraction (XRD) measurements on RMnO3 (R=Dy, Ho and Lu) reveals that varying structural changes occurs for different R ions. Large lattice changes (orthorhomb…
Emergence of charge order from the vortex state of a high temperature superconductor
T. Wu, H. Mayaffre, S. Kramer +8
Evidence is mounting that charge order competes with superconductivity in high Tc cuprates. Whether this has any relationship to the pairing mechanism is unknown since neither the…
Ferroelectricity in Single Crystal InMnO3
T. Yu, P. Gao, T. Wu +2
Single crystal synthesis, structure, electric polarization and heat capacity measurements on hexagonal InMnO3 show that this small R ion in the RMnO3 series is ferroelectric (space…
